ELECTRIC HEATER.

Application filed March 11, 1921.

T 0 all whomz't may concern:

Be it known that I, LAURENCE J. TRACY, a citizen of the United States and resident of St. Louis, Missouri. have invented certain new anduseful Improvements in Electric Heaters, of which the following is a specification.

This invention relates to improvements in electric heaters, and has for its object a heater comprising'an outer shell, a drum located in said shell, and suitably spaced apart, aplurality of air circulating flues passing through the drum, and a heating element located in the drum by which the air is heated during its circulation through the fines.

- A further object of my invention is to construct a heater which is both efiicient as a heater as well as ornamental and the essential feature is to heat the air as it circulates through the same.

The heating unit consists preferably of one or a number of electric coils and so wired as to be operated independently or collectively and an indicator light wired to the coil to indicate the operativeness of the heating unit.

Figure 1, is a vertical sectional view of my improved heater.

Fig; 2, is a top plan view of the same with the lid or cover removed.

Fig. 3, is a horizontal sectional view taken on. the line 33 of Fig. 1.

Fig. 4;, is a diagrammatic View of the heating unit and its circuit.

In the general construction of my improved heater I providean outer shell 5, at the bottom of which is located a flange or shield 6, and on the top of the shell is located a. lid. or cover 7, the same being constructed of a grille work or the like so as to provide free passage for the circulation and outlet of the heated air.

Inside of the shell 5 and suitably spaced from the same is a drum 8, the same having a bottom 9 and a top 10, both top and bottom is provided with a plurality of holes in which is firmly fixed the ends of pipes 11, which act as air circulating flues, per- Specification of Letters Patent.

air into the interior of the drum said air coming in direct contact with the heating unit. This air then passes out through openings 14 formed around the upper periphery of said drum and is discharged into the pas sage 15 formed between the drum and the outer, shell.

Through this passage air is also permitted to circulate and intermingle with the heated air ipassing out through the openings 14, at the same time keeping the outer shell comparatively cool so that the heater may be conveniently handled.

The heater is supported on suitable standards '16 of any desirable construction and the same are of such height asto provide sufficient space between the fioor line and the bottom 17 of the shield 6.-

On the top of the cover is placed a suitable ornamentation 18 in which is an electric lamp 19, the same being electrically connected to one of the coils comprising the heating unit.

Referring to Fig. '4, the diagrammatic view, I illustrate the circuit for controlling the heating unit, in this instance two coils are shown a and 7). The coil a is connected to t-he'wire c and the wire at, the same connected to a plug (2 which may be inserted in any convenient socket. The coil 6 has its one end connected by means of the wire f to the wire 0, the other end to a wire g to a switch it and from the switch by a wire 2' to a plug 677- By this arrangement either one or both of the coils may be operated either independently or collectively. Should all of the coils be in operation and the heat become too excessive, the coil 1) may be cut out by the operation of the switch h thus leaving only one coil in operation. The lamp 19 whichis on top of the cover is connectedby means of the wires j and 7a to the lower coil as illustrated. This light is at all times illuminated While the coil is in operation; thus this lamp acts as an indicator to show the coil is in operation as well as an ornament in the 100m, also indicating the location of the heater especially when entering a dark un-illuminated room.

The wires which lead from the coil are conveniently placed as that indicated by the numeral 20.

Having fully described my invention what I claim is:

1. An electric heater comprising an outer shell, a drum. located in the outer shell and suitably spaced therefrom, a plurality of air circulating flues passing through said drum and a heating unitv located centrally in said drum, substantially as specified. r

2. A heater of the character described comprising a shell, a shield located at the bottom of said shell, a drum located inside of the shell and suitably spaced therefrom, a plurality of fines passing through said drum, openings formedin the bottomot' the drum and located near the center and openings formed on the periphery near the top of said drum, an ornamental cover placed on the top of the shell a heating coil positioned in the drumand a l ight located on the cover and in circuit with the coil, substantially as specified.

3. A heater of the class described comprising a shell, a drum located therein, said drum having a top and, a bottom, Hues passing through the drum and supported by the top and bottom, the upper end of the drum having its periphery provided with outlet openings, the bottom provided with openings for the admission of air into the drum and to be in direct comn'iunication with the heating unit and ornamental open cover located on the top of the shell, an electric heat unit placed in the drum for heating the air as it circulates through the drum, substantially as specified.

l. A device of the character described comprising a heater consisting of an outer shell, a drum located inthe same and suitably spaced from the outer shell, said drum having two end heads, Hues supported by the end heads and passing through the drum providing air circulating passages, a sectional heating coil located in the drum and so wired as to be operated separately and collectively and an independent light in con nection with said coil, substantially as specified.

' In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
